Called the X1 Prototype, it's designed by Red Bull F1 guru Adrian Newey to be the star attraction of Gran Turismo 5, the much-delayed Playstation game.

The X1 is powered by a 3.0-litre twin turbo V6 engine that produces 1105kW. The wheels and cockpit are fared in with bodywork for aerodynamics and there's a fan at the rear to help suck the car to the road. Coupled with its light weight (550 kilograms), the X1 can accelerate to 450km/h and from 0-100km/h in 1.4 seconds.
